Kōwhai’s golden flowers, delicate foliage, and adaptability make it a standout addition to gardens, pots, or even as a shade tree. It’s a quintessential Kiwi favourite with functional and aesthetic appeal.
Position
Plant in full sun to part shade. Kōwhai thrives in deeply worked, organically enriched soil that is well-draining yet moisture-retentive.
Prepare Soil
Garden: Enrich soil with compost or organic matter, ensuring it is well-draining to prevent waterlogging.
Pots: Use a premium potting mix with added slow-release fertiliser to support growth.
Feed
Garden: Fertilise in early spring with a balanced fertiliser to encourage flowering and healthy foliage.
Pots: Use a liquid fertiliser every four weeks during the growing season for vibrant blooms.
Watering & Mulching
Water deeply during dry periods, particularly in the first year of growth. Mulch around the base with bark or organic matter to retain moisture and suppress weeds.
Protection
Kōwhai is hardy but benefits from protection against strong winds when young. Watch for caterpillars, which may occasionally nibble on the foliage.
Harvest
Collect the distinctive seed pods once they mature and dry. Sow the seeds after lightly scarifying them to encourage germination.
